Abstract: A shaft lock includes a radially inner rotor part that is coaxially connected to a shaft having a rotational axis and a fixed stator part that at least partially encloses the rotor part. In a locking state and in a holding state, an interference-fit connection between the rotor part and the stator part is produced by a plurality of locking bodies, and the interference-fit connection is cancelable by a transition into an unlocking state. To produce the interference-fit connection, each of the plurality of locking bodies are partially engageable in an interference-fit manner in a respective receiving geometry of the rotor part by rotation of a substantially hollow-cylindrical locking ring that coaxially encloses the stator part in a partially radially outer-lying manner.

When the internal tooth and the engagement surface abut against each other, the internal tooth and the engagement surface are engaged, and the outer member and the inner member integrally turn.

Abstract: A soft action clutch uses a helical spring attached to a pulley at one end and free at the other end. In a relaxed state, preferably, the helical spring presses outwardly pushing a brake pad assembly against a fixed outer field cup braking the pulley. To serve as a clutch, a rotor has a pole face to magnetically draw the helical spring towards it. The resulting friction between the rotor and helical spring causes the spring to wrap down on a spring loaded friction disk. The wrap down compresses the friction disk radially, creating two frictional links from the friction disk to the rotor and the pulley, respectively.

Abstract: A brake and clutch assembly mounted on an electric motor's drive shaft comprises, in succession and outwardly from the motor, a brake pad, a drive disk, a clutch plate, a pulley, a compression spring and an end cap. The drive disk includes a sleeve with the clutch plate and the pulley being slidably mounted thereon.

The spring biases the pulley, clutch plate and disk drive towards the brake pad thereby frictionally retaining the drive disk thereagainst when the motor is not operating and preventing the components from rotating. When the motor is started, the pin climbs out of the bottom of the recess by pushing the drive disk against the spring's force thereby axially displacing slightly the disk drive away from the brake pad such that the pin rotates the drive disk which frictionally drives the clutch plate and the pulley.

Abstract: A relatively light duty cone type clutch suitable for use in window blind or shade mechanisms is disclosed. As contrasted with conventional cone type clutches, the disclosed embodiment includes a plurality of radially arranged conically shaped rollers which are maintained in position by a spider forming part of a motion input pulley. The rollers are urged into engaged condition between a fixed clutch body and a polygonally shaped motion output core. The clutch is maintained in engaged condition by residual torque upon the output core provided by the weight of the unwound portion of the shade or blind. Upon the occurrence of rotary motion imparted to the pulley in either direction, the movement of the spider dislodges the rollers in an axial direction from engagement with the clutch body, following which motion is transmitted through the spider and rollers directly to the output core. When motion ceases, the rollers are returned to static position by a pressure washer carried by the spider.
